Modifying the composition of Contact person name

Modifying the composition of Contact person name

In Contact person list view and in the detailed view, the Contact person name is a composition of the first name and the last name.
I want to change it, because in our country some last name have a prefix like "Van Dijken", the "Van" is a prefix and we want to put the prefix in a seperate field. The Contact person name in the list view and in the detailed view should be composed of the first name + the prefix + the last name.
How can I do that?
